Self-lifting elevator shaft protection operation platform suitable for multiple calibers

Abstract

The invention discloses a self-lifting elevator shaft protection operation platform suitable for multiple calibers. The self-lifting elevator shaft protection operation platform comprises a lower stair and stand columns. The lower stair comprises two first inclined pipes which are obliquely arranged, second inclined pipes which are parallel to each other are further arranged between the two first inclined pipes, and a plurality of corridor stair steps are arranged between one of the first inclined pipes and the second inclined pipes; the self-lifting elevator shaft protection operation platform further comprises a fourth external thread steel pipe movably penetrating through the first inclined pipe, the second inclined pipes and the first inclined pipe in sequence; a plurality of stand columns are arranged in the circumferential direction and used for supporting the lower stair; and the multiple stand columns are provided with a plurality of horizontal telescopic pipes which are sequentially encircled to form a ring, and the multiple horizontal telescopic pipes are detachably connected with the stand columns. By the adoption of the scheme, the first inclined pipes can be suitable for different elevator shaft lengths, the fourth external thread steel pipe can be suitable for different elevator shaft widths, and the horizontal telescopic pipes can be suitable for different elevator shaft calibers, so that the purposes of being suitable for various elevator shaft mouths and capable of being turned over are achieved.

Description

technical field [0001] The invention relates to the technical field of building construction safety protection, in particular to a multi-diameter self-elevating elevator shaft protection operating platform. Background technique [0002] At present, new buildings are often mainly high-rise buildings, and elevators are widely used in high-rise buildings, which undoubtedly adds risks to the construction of elevator shafts. Elevator well protection operation platform is a protection and operation platform set up on the elevator wellhead of each floor during the construction of the main structure in high-rise buildings, so as to protect the elevator wellhead, and at the same time facilitate the support, reinforcement and removal of the inner peripheral wall formwork of the elevator well Therefore, the elevator shaft protective operating platform is very important for the safe construction in and around the elevator shaft. [0003] At present, the most common protective operating...
